When the cutting edge width b reached in the case of the milling mode No.
the wear of cutting edge increases with the increasing cutting length .
3) revealed that the increase of cutting length L and width b of cutting edge cause decreasing of the processed surface quality.
A high quality cutting edge was achieved using lower feed rates [v.
The aim of the experiment was to determine the influence of the cutting edge quality obtained by grinding on cutting tool life.
Gerhard Huber, Seco's sales and customer care manager, sums it up: "The extremely stable cutting edge
of the round insert is the key to success in terms of productivity.
New octagonal inserts (shown at right) offer eight cutting edges, each with 45-degree lead angles, for more economical milling applications.
Inserts combining helical cutting edges, a large axial angle, and a rib-type rake face design offer a self-balanced, stable tool for cost reduction and high performance in semi-finishing and finishing.
This twisted geometry doubles the number of cutting edges of deep face grooving tools.
A unique twist in the insert geometry doubles the number of cutting edges for deep cutoff tools.
The double-negative insert allows the strongest possible cutting edges, able to withstand heavy chiploads and high cutting forces.
Negative radial rake provides strong cutting edges, while positive rake creates a shearing action.
